Method and classification for resistance to attack by boiling aqueous sodium carbonate and sodium hydroxide solution.

This International Standard specifies

  1. a method for determining the resistance of glass to attack by a boiling aqueous solution of sodium carbonate and sodium hydroxide. The resistance is measured inversely by the loss in mass per unit surface area of the glass;
  2. a classification of glass according to the alkali resistance determined by the method of this International Standard.

NOTE 1 The method of test according to this International Standard is also applicable for determining the alkali resistance of glass ceramics.
